WILLIAM R. MERRIOK, OF EVANSVILLE, INDIANA.

COOKING-STOVE.

Application filed September 10, 1907.

To all whom it may concern:

Be it known that I, IVILLIAM R. MERRICK, a citizen of the United States, residing at Evansville, county of Vanderburg, and State of Indiana, have invented certain new and useful Improvements in Cooking-Stoves, of which the following is a specification.

My invention relates to cooking stoves.

A difficulty heretofore experienced with cooking and other stoves is that when the lid is lifted to supply the fire-box with coal, if the flue damper is so arranged that the products of combustion and heat may be directly passed to the fire-box and flue, the gases, smoke, etc. do not pass through the stove lid opening, but if the flue damper is closed so that the products of combustion have to pass around the oven before entering the flue (a common arrangement in cooking stoves) and the stove lid is raised, the tendency of the draft is to take the shortest course and smoke, dust, soot, etcf'rise through the stove lid opening, which is, of course, very objectionable.

Another disadvantage incident to cooking stoves is that when the ash pan is pulled out, the gases and the draft may tend to pass down instead of up, and hence disseminate, to the discomfort of the person.

The present invention has for its objects the provision of means to prevent the foregoing objections and also to regulate the heat under the oven, and this is accomplished by the provision of a damper arranged in a novel fashion to control the draft from the ash pit and space below the irebox to the hot air flue or duct under the oven, as will more fully appear hereinafter.

In the accompanying drawings Figure 1 is a sectional elevation of a cooking stove equipped with my invention; and F ig. 2 is a horizontal section on line 2-2of Fig. 1.

The fire-box is shown at 1, the stove lid opening at 2, the'ash pan at 3the oven at 4,V

and the take-ofi` flue at 5.

As usual in cooking stoves, three sides of the oven are surrounded by a hot air flue 6 so that the hot air may pass around the oven before entering the flue 5, which circuit is controlled by the position of the damper 7 in flue 5, said damper determining whether the specification of Letters Patent.

Patented April 21, 1908.

Serial No. 392,172.

products of combustion will pass directly from the fire to the iiue 5 or be compelled to pass to said flue via flue 6.

I provide a baffle S underneath the oven so that the heat will be deflected and spread underneath the oven before being allowed to pass to the exit mouth 9 leading into flue 5.

Instead of making the front end of the lower part of flue bliin as is now done, I provide an opening 10 leading into the ash pit above the ash pan and this is equipped with a damper 1l operated by a suitable handle 12 adjacent the ash pan.

Then the damper 11 is closed, the hot air circulates around the oven and passes out through opening 9 into flue 5 in a wellknown manner, but when this damper is open, and the stove lid opening 2 is exposed, damper 7 boing closed, instead of the gases, smoke, etc., passing upwardly, the draft Will be downward through the stove lid opening, and through the fire, via the ash pit and through the opening 1() to the opening t), so that the gases, smoke, etc. are carried oil and do not escape through the opening 2. This damper provides means for regulating the amount of heat supplied to the oven, because according as the damper is opened to a greater or lesser extent, so will the heat pass to a greater or lesser extent around the oven.

On pulling out of the ash pan and opening of the damper 11, the draft will be inwardly from the exterior of the stove, via the space above the ash pan, to the opening 10 so that the gases and dust in the ash pit will be carried off` and in no manner afford discomfort to the person pulling out the ash p an.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

l. In a cooking stove, the combination with a fire-box and an as h pit below the 'firebox and having means for access thereto, of an oven, a flue around the oven and in comniunication with the fire-box, a take-off fiue in communication with the flue aforesaid below the oven, said oven heating flue opening into the ash pit below the oven, and a damper controlling the opening into, the ash pit.

2. In a cooking stove, the combination controlling the opening into the take-off Hue with an oven having a flue therearound, and above the oven. 10 a fire-box in communication with said iiue, In testimony whereof, I hereunto affix my of an ash pit into which said flue opens below signature in presence of two witnesses.
